D. (a) - (iii) , (b) - (iv) , (c) - (ii) , (d) - (i)

Answer

To solve the question of matching the organs with their respective diseases, we will analyze each disease and identify the organ responsible for it step by step.

### Step-by-Step Solution:

1. **Identify Addison's Disease**:
- Addison's disease is caused by the hyposecretion of steroid hormones, particularly cortisol and aldosterone.
- These hormones are secreted by the **Adrenal Cortex**.
- **Match**: Addison's disease → Adrenal Cortex (iii).

2. **Identify Tetany**:
- Tetany is caused by the hyposecretion of parathormone, which is crucial for calcium reabsorption.
- This hormone is secreted by the **Parathyroid Gland**.
- **Match**: Tetany → Parathyroid (iv).

3. **Identify Acromegaly**:
- Acromegaly is a hormonal disorder resulting from the oversecretion of growth hormone.
- This hormone is secreted by the **Pituitary Gland**.
- **Match**: Acromegaly → Pituitary (i).

4. **Identify Myxedema**:
- Myxedema, also known as Gull's disease, occurs due to a deficiency of thyroid hormones.
- These hormones are produced by the **Thyroid Gland**.
- **Match**: Myxedema → Thyroid (ii).

### Summary of Matches:
- (a) Addison's disease → (iii) Adrenal Cortex
- (b) Tetany → (iv) Parathyroid
- (c) Acromegaly → (i) Pituitary
- (d) Myxedema → (ii) Thyroid

### Final Answer:
The correct combination is:
- A with iii
- B with iv
- C with i
- D with ii

Thus, the appropriate combination is **(a) with (iii), (b) with (iv), (c) with (i), (d) with (ii)**.
